The wife wanted to get the eldest girl (7) some Wonder Woman. She picked up the trade of the first few issues of the New52 run.

Having not reviewed it before purchase, turns out it may be a touch intense, maybe, for a 7 year old. I kinda like it, but I'm a sucker for new visual perspectives on the Greek pantheon (or any other, really).

So, I found this:

which seems like it may know things about which it speaks, but, I'm tossing out the question anyway.

For a kid?

The George Perez run is probably best.

But honestly, I'd recommend Marvel's old Spider-Girl series over anything Wonder Woman. There really aren't that many Wonder Woman stories that are both good and all-ages friendly.

This is a little sad. Johns' Pre-"New52" Green Lantern were my first comic purchases on my iPad. His run of Green Lantern has been some great space opera and is clearly the inspiration of the excellent Green Lantern animated series now on Cartoon Network.
